New Gen2 Fortitude Leaking out of box

I received my Gen2 Fortitude .22cal, on 03-31-2020, when I received the rifle it had Zero air in it. So I pumped it up to 2000psi with my Hill mk4 hand pump, and in three days, it had leaked down to 1600psi. I pulled off the stock and sprayed with soapy water, and see some bubbling at the Stock's Hold down screw/Nut, this looks like it is the front hold down bolt for the trigger group. Has anyone heard of this rifle leaking here, or have fixed this problem? any Info would be much appreciated. My thought is to shoot the air out of it. and remove the Bolt/nut and put some Teflon tape on it, and reinstall it, then retest for a leak. Any ideas?
 
 There should be no pressure at that screw. If it is like the Discovery and some other similar guns, which it likely is, a leak there would indicate an internal failure of one of the valve or gauge block o-rings that keep the pressure in the tube. The gun needs to be completely disassembled to replace them.

If it were me I would fill the gun with air and shoot it down a few times first to see if it would seal up by itself before I took any other action.

With a leak that small you may as well be shooting pellets out of it for a few fills.


 
ok Then, I think I will be sending it back, for a refund, until I know this issue is fixed. Neither my Marauder synrod and Prod never had a single issue with any leaks what so ever.

You have got lucky then. O-rings are an expendable item and will eventually need replacement on your other guns. If you like the Fort, return for a replacement and try one more before giving up on the platform.
 
The regulator spans the hole for the trigger assy, but basically the same concept as mentioned above.


Agree with FuzzyGrub about the regulator position but there is a small weep hole in the tube next to the front trigger screw for regulator equalization that will also bubble.

The weep hole is drilled in the Gen 2 air tube, but just leaked through the threads on the Gen 1. It will only bubble until filled with water. If it is a continuous stream, it is leaking. Either the outer O-rings or inner to reg are leaking. The valve, regulator, and gauge block are a mixture of -113 and -016 O-rings, but don't know what the internal one to reg are. Crosman hasn't released the schematic, but if you talk to the Customer Service, they will usually help you.

Crosman did allot more deburing on the air tube for Gen 2, but in addition to gauge hole, that threaded trigger hole can slice O-rings.



PS; I'm not sure what hours, if any, Crosman CS is open these days.


 
I have searched Crossman's site for a exploded view of the Fortitude and cannot find one, I see the Maximus Exploded view/parts list, which is a little different, but has some similarities, I would think since these two guns are similar, and i am not sure what is the same and what is not other than the internal Regulator, as far as other parts go. I've seen on Maximus guns when they have a leak at same place my guns leaks they wrap the Gauge Block, threads with Yellow PTFE Gas line seal tape. I may try this, and shoot the hell out of it before sending it back to see if I can get it to stop leaking. I did not really want to Open a New gun to have to re-oring the Gauge port block that is internal. I am sure it is probably very easy. But I have Not even shot this rifle yet, just dry fired it, as the Leak stopped me, so Not even sure if this gun is accurate, other then the 10yard target that shipped with this rifle is pretty tight.


 
I had sent a email to Crosman Customer support a couple days ago they got back with me saying where to test for the soapy water, and I replied back to them, asking them if they were Open to resolve this issue and how long it would take. This was their message to me.

"It would be covered under warranty

Some checks are to take a little soapy water and put it around the fill adapter and the gauge to see if that is the location. If it is not there is could be the valve in side. Try giving a good jolt of air sometimes that helps the valve from sticking if that is the case. If that does not work we would have you send it back to Crosman, these are checks to see if we can locate the problem.


Thank you for contacting Crosman Corporation!"

My reply to them.

"I tried the soapy water, and found it leaking at where the Gauge adaptor goes into the gun as the bubble are coming from between the Air rube and the E tube and the moderator tube. At the Gauge adaptor area. All I have is a Hill Hand Pump MkIV, I don’t have a compressor. I may try to pump it up to 3000psi and shoot it down to 1000psi a couple of times to see if it stops the air leak. 

Do you have a exploded view of the Fortitude? I cannot find it. 

If I were to send it back to Crosman, Are you open? To get this resolved? What would be the turn around? And do you test the rifle for leaks before you ship the new one out, and if so, how long do you leave it pressured up before shipment? "

I am looking forward to their reply.


 
If it is leaking from the trigger assy screw or the vent hole, the gauge block is not causing it.

If it is leaking by the gauge hole, it is probably the gauge block outer O-rings, think they are -113, but maybe -016. The gauge is 1/8" NPT which does use tape as it screws into the female end of the adapter. The male end adater that threads into the gauge block, is a 1/8" straight thread and should NOT have tape. There is an O-ring that sits in the bottom and seals. It is a -009.


 
I filled The Fortitude back Up to 2000psi, and shot it yesterday 20rounds, it was raining outside, I was under my car port shooting at about 60F degrees shooting Crosman 14.3 domed ultra magnum pellets. Then I filled it back up to 2000psi, and it held overnight. So I ill get about 500 rounds through it, and fill back to 2000psi, then do a one week leak down test, and see what happens. Since I imagine Crosman will probably be running a skeleton crew, might as well give the Fortitude a Good thorough test. I inspected the Baffles and shroud cap for Pellet Clipping, None, Cleaned the Barrel pulled 20 oiled patches, through and 10 dry ones, Barrel was Very dirty, Barrel was Much Dirtier, Gritty when pulling Patches through, Dirtier than my Synrod or Prod was, But the barrel Looks Clean Now. I Straightened the Barrel band, as it was way off, to the Left pulling the Shroud/Barrel that direction, and took out all of the Slop and there was a Lot of Movement/slop between the Barrel Shroud, within the Barrel Band, the POI would have been all over the place this way, I was surprised how much movement there was in the muzzle end of Barrel, when I had the shroud off, and i was Just as surprised at the amount of Movement in the Shroud within the Barrel Band, This was a LOT of Movement here, I have Zero Movement Now, so should be better POI stability than it was, But No reference as I didnt shoot it that way with a sighted in scope. I have Not yet done the trigger, as I want to see how this gun performs without me Opening the gun in case it has to go in for a return/replacement. I checked the Foster fitting fill probe, to make sure it was tight and it was, and check the Gauge and gauge block also for tightness, they were tight. Maybe a oring needed to seat or lube spread? I am Hoping the leak is gone. But I will follow up for those interested in a New Fortitude Gen2.
